120 When requested by the initiating Prediction function the initiating Broadband signalling function sends a B-IAM (Broadband Initial Address Message) towards the remote Broadband signalling function. The called party number addresses the remote Prediction function. The requested broadband transfer capability matches the NB transmission medium capability configured for the route. For basic emulation of N-SS7 the broadband transfer capability requirement is for 64 kbit/s constant bit rate. However, if the N-SS7 route has been configured for selection under more stringent N-SS7 criteria then the broadband transfer capability may be tailored to suit the N-SS7 requirement (e.g. speech, 3.1 kHz, Audio, Group 2/3 facsimile, etc.) depending on the capabilities of the broadband signalling. Additionally there is specific information included in the B-IAM to indicate that bandwidth is being requested to support N-SS7. This information conveys the corresponding N-SS7 route/circuit identity (OPC/DPC/CIC) (originating point code/destinction point code/circuit identification code) from the initiating Prediction function to the remote Prediction function and may be embedded in the Prediction function addressing scheme or may be a new parameter with parameter compatibility information which indicates “pass-on” and “release call if pass-on not possible”. To protect the remote Prediction function from unauthorised access the B-IAM includes the calling line identity which identifies the initiating Prediction function. For additional protection the Closed User Group (CUG) supplementary service may be utilised.
130/140 Basic B-ISUP Behaviour.
150 In addition to Basic B-ISUP behaviour, the remote Broadband signalling function indicates to the remote Prediction function that that additional bandwidth is required to meet the current narrowband traffic demand. This indication includes information about the propagation delay of the bearer (if supported by the Broadband signalling protocol, e.g. B-ISUP Propagation delay counter parameter). If the Prediction functions are being protected by the CUG supplementary service then invalid (failed CUG) requests are not passed to the remote Prediction function.
160/170/180 Basic B-ISUP Behaviour.
190 On receiving the indication from the remote Broadband signalling function that additional bandwidth is required to meet the current narrowband traffic demand the remote Prediction function checks the requirements against its own data. To accept the request the remote Prediction function requests the remote Broadband signalling function to accept the call. If the request is accepted, the propagation delay (if available) is passed to the Narrowband signalling function for use during subsequent narrowband call establishment signalling. Under exceptional conditions, the remote Prediction function may reject the request and indicate the reason for rejection. Reasons for rejection include: unrecognised initiating Prediction function (CLI check failed); route identified by OPC/DPC not configured at remote Narrowband signalling function; identified CIC not configured at remote Narrowband signalling function; bandwidth already allocated to identified CIC; and originator of request is not “initiator” for this route.
200 The Narrowband signalling function records the bearer propagation delay as data against the particular CIC for use during narrowband call establishment signalling (when the CIC is subsequently unblocked).
210 To accept the call a B-ANM is returned towards the initiating Broadband signalling function. To reject the call a B-REL including specific rejection information is returned towards the initiating Broadband signalling function. This information identifies the reason for rejection and has parameter compatibility information which indicates “pass-on” and “discard parameter if pass-on not possible”.
220 Basic B-ISUP Behaviour.
230 In addition to Basic B-ISUP behaviour, the initiating Broadband signalling function indicates to the initiating Prediction function that that the requested additional bandwidth is available. This indication includes information about the propagation delay of the bearer (if supported by the Broadband signalling protocol, e.g. B-ISUP Call history information parameter). If the call request has failed then the initiating Broadband signalling function indicates to the initiating Prediction function the reason for rejection (either as received from the remote Prediction function or as determined by basic call failure).
240 Once the bandwidth is confirmed the initiating Prediction function passes the propagation delay (if available) to the Narrow band signalling function for use during narrowband call establishment signalling and then requests the initiating Narrowband circuit management function to unblock the CIC for N-SS7 call control to use. If the initiating Prediction function is aware that bandwidth has been made available for several CICs then the narrowband circuit group unblocking procedures may be invoked. Any failure to establish bandwidth is analysed by the initiating Prediction function. Basic broadband call establishment failure may result in the initiating Prediction function making another attempt to establish bandwidth. Specific errors received from the remote Prediction function are reported to system management as faults.
250 The Narrowband signalling function records the bearer propagation as data against the particular CIC for use during narrowband call establishment signalling (when the CIC is subsequently unblocked).
260 On request from the initiating Prediction function the initiating Narrowband circuit management function shall initiate unblocking of the CIC via normal procedures in N-SS7. Interaction with existing MMI and N-SS7 blocking/unblocking procedures is required.
270 On request from the initiating Narrowband circuit management function normal N-SS7 unblocking procedures are invoked.
280 Normal N-SS7 unblocking procedures including an indication to the remote Narrowband circuit management function that the CIC is available for use by N-SS7.
290 Normal N-SS7 unblocking procedures including an indication to the initiating Narrowband circuit management function that the CIC is available for use by N-SS7.
300/310 The remote Narrowband circuit management function advises the remote Prediction function that the CIC is unblocked.
320/330 The initiating Narrowband circuit management function advises the initiating Prediction function that the CIC is unblocked.
510-710 Releasing Surplus Bandwidth
510 When the initiating Prediction function determines that the provided bandwidth is more than required it requests the initiating Narrowband circuit management function to initiate narrowband circuit blocking procedures. If multiple circuit bandwidth can be released then the narrowband circuit group blocking procedures may be invoked.
520 On request from the initiating Prediction function the initiating Narrowband circuit management function shall initiate blocking of the CIC(s) via normal procedures in N-SS7. Interaction with existing MMI and N-SS7 blocking/unblocking procedures is required.
530 On request from the initiating Narrowband circuit management function normal N-SS7 blocking procedures are invoked.
540 Normal N-SS7 blocking procedures including an indication to the remote Narrowband circuit management function that the CIC has been blocked by N-SS7.
550 Normal N-SS7 unblocking procedures including an indication to the initiating Narrowband circuit management function that the CIC has been blocked by N-SS7.
560 The Narrowband circuit management function keeps the Prediction function aware of CIC status. If the CIC is already idle (not being used for a call) then the indication to the Prediction function will identify “blocked/free” status.
570 The Prediction Function Monitors CIC Status.
580/590 As 560/570.
600 The Narrowband signalling function keeps the Narrowband circuit management function aware of CIC status (normal action). In particular, if the CIC was being used for a call when the blocking procedures were completed, a CIC free indication will be made when the call clears.
610 The Narrowband circuit management function keeps the Prediction function aware of CIC status.
620 The Prediction Function Monitors CIC Status.
630/640 As 600/610.
650 Once the initiating Prediction function is aware that the CIC is both blocked and free, then it initiates release of the bandwidth by sending a release bandwidth request to the initiating Broadband signalling function. Alternatively, if determined by the initiating Prediction function the bandwidth release procedure may be aborted at this stage and the bandwidth returned to service by invoking the N-SS7 procedures to unblocking the CIC.
660 When the release bandwidth request is received the initiating Broadband signalling function initiates normal broadband release procedures by sending a B-REL.
670/680 Basic B-ISUP Behaviour.
690 In addition to the Basic B-ISUP behaviour the remote Broadband signalling function shall send a bandwidth release indication to the remote Prediction function.
700 Basic B-ISUP Behaviour.
710 On receipt of the bandwidth released indication, if the CIC is blocked and free the remote Prediction function shall note that bandwidth is no longer allocated to the CIC.
Receipt of Unexpected Bandwidth Released Indication at a Prediction Function
If the Prediction function receives a bandwidth released indication and the CIC is not blocked the following applies.
At a remote Prediction function, the remote Narrowband circuit management function is advised that the CIC is faulty and unavailable for calls. Any narrowband call in progress is released using N-SS7 procedures. The exceptional condition remains in the remote Narrowband circuit management function until the CIC status returns to blocked/free as a result of actions at the initiating Prediction function.
At an initiating Prediction function, the initiating Narrowband circuit management function is advised to initiate blocking of the CIC. Any narrowband call in progress is released using N-SS7 procedures. Once blocking is confirmed, the initiating Prediction function may decide to re-establish the lost bandwidth using the procedures described above.
The invention is applicable to many other types of network. For example, in an IP network a predictive algorithm might be used to control, e.g., the proportion of network bandwidth allocated to telephony, to fax, to data services at different times.
